Md Tahmid Tanjim R.
Full-Stack Flutter Developer | MVPs, Business Apps & Real-Time Feature
🚀 Need a Flutter developer who can build your ✅MVP end to end: the app, the backend, the admin side, and the real-time features? You're in the right place. I build production-ready Flutter apps with a clean UI, a solid Firebase/Node.js backend, and architecture that another developer can pick up without a rewrite. I work with startups, small businesses, and agencies who want one reliable developer instead of juggling a mobile dev and a backend dev. Most Flutter developers stop at the UI. I also handle ✅auth, ✅databases, ✅role-based access, ✅cloud functions, and ✅real-time audio/video, including native Kotlin bridges when an SDK has no Flutter plugin. 🔗How I Help Clients - MVP development from idea to working iOS/Android build - Business apps: client portals, dashboards, project and order tracking, admin panels - Backend: Firebase (Auth, Firestore, Storage, Cloud Functions) and Node.js/Express REST APIs - Multi-role apps: admin / staff / client access with secure data rules - Real-time features: voice rooms, live streaming, group video, chat (Agora, LiveKit, WebRTC) - Fixing stuck integrations: native build errors, SDK conflicts, threading and permission bugs - Clean state management (Riverpod, Provider, BLoC) and full source-code handoff Highlighted Projects - Business Management App (USA): Flutter MVP for a remodeling company. Role-based admin/client login, client and project management, progress dashboard, photo and document uploads, material catalog. Firebase backend, delivered in milestones with working builds at each stage. - LiveRoom: Live voice room and live streaming app. Flutter, Firebase, Riverpod, Agora. - LiveParty: group video party platform built on LiveKit. - Spark and NovaTrade Pro: a Flutter dating app and a BLoC-based trading terminal UI (see portfolio). ⚙️Skills & Technologies Flutter, Dart, Firebase (Auth, Firestore, Storage, Cloud Functions), Node.js, Express, REST APIs, Riverpod, Provider, BLoC, WebRTC, Agora, LiveKit, WebSockets, Kotlin MethodChannel/EventChannel, Hive, SQLite, Git/GitHub ✅How I Work I break the project into clear milestones, show a working build at each one, and communicate in plain language. At the end you get everything: source code, Firebase project, and GitHub access.
